Your letter

Do you need to tell people you used dictation software? That you got feedback on a note? These letters come from a place of care — if disclosure feels right, a warm PS does it. The button adds one; click again for a different wording, for example "By the way, I used a machine to help pen this."

What makes a letter look real
  • Blue over black. Real pens rarely write pure black; blue ink reads as a person, black as a printer.
  • One hand throughout. Mixing fonts looks fancy but backfires — on the FarmKind run, "Geoffrey" got two different f's in one word and it read as strange. Same hand, whole letter.
  • Imperfection, sparingly. A slightly wandering baseline, uneven margins, one crossed-out word. Perfect uniformity is the giveaway — this preview is more even than the machine's real output, which helps.
  • Real paper, real pen. A ballpoint or gel pen leaves pressure marks and ink pooling that no printer makes. Heavier paper feels like a decision.
  • The envelope sells it. Hand-addressed, a real stamp, maybe slightly crooked. The envelope is read first.
  • A PS reads personal. Afterthoughts are human. It is also the honest place to say a machine helped.
  • Signature by actual hand if you can — even one real pen stroke changes the object.
Machine settings — the working recipe
Recorded 2026-08-12 during the timed FarmKind test: Dear Geoffrey on yellow A5 (half sheet), Premium Ultra 34, on the iAuto at the Animal Rising office. Full copy in the vault note "handwriting machine uunatek iauto".
  • Machine: pen up 4 · pen down 8 · installation pen position 7 · empty travel enabled (pen up 0, threshold 10 mm) · offsets horizontal −5, vertical −55 · multiple feed 2
  • Software: resolution ratio "Resolution" · speed Custom — writing 1500, movement 1000 · unit inches · image limit 4000 px · tool size 0.3 mm · connection timeout 5, automatic connection on, reconnect off · complete pop-up on, prompt sound off
  • Character: add left 0 · add right 0 · baseline 100 · random float up/down ≈ 4th notch · amplitudes 1, squiggle 2 · initial random placement 0 · width automatic · nib none (0, 0)
  • Font deformation: size 95–100 · spacing 95–100 · tilt −5 to 5 · vertical stretch 95–100 · horizontal stretch 95–100
  • Stroke deformation (sliders, by eye): angular ≈ 20% · length ≈ 33–35% · performance ≈ 25%
  • Measured result: the 422-character Dear Geoffrey A5 letter took 8 min writing + ~20 s page change = 8 min 20 s per letter (0.88 chars/s — the timing panel's calibrated defaults). 100 such letters ≈ 14 hours of machine time.

Machine timing — iAuto

Calibrated 2026-08-12 from a real timed run: the 422-character Dear Geoffrey letter on yellow A5, at the settings in the recipe panel below, took 8 minutes of writing plus about 20 seconds to start the next page — 0.88 characters per second, 8 min 20 s per letter of that size. Rule of thumb: minutes ≈ characters ÷ 53. Re-time and nudge these if the machine settings change. Print time = characters ÷ speed, plus feed time per page.

Size ladder

"Size" = the height of one character — the font's full em box, capital top to descender tail (like a Word font size, but in mm; 5.0 mm ≈ 14 pt). Line-to-line distance = size × line spacing.
